Yeah, unfortunately certain hardrives have little "features" built into them that put the drives to sleep. They can be tricky to get at. Gawd... I can't remember the utility Western Digital uses.
I think the place to look for this kind of crap is in the Device Manager, navigate to the hard disk entries and poke around the Properties of the installed drives.
Unfortunately (and don't quote me on this) the so called "Green" drives may have these power features built right into the firmware and I don't know if they are accessible. Maybe just try to move the mouse around or something every few minutes to keep things from falling asleep if that is the case.
Also on my (Acer) laptop I did a clean install of windows and my hard drive and encountered a familiar problem I had solve previously (after I had done a massive cleanup/disabling of what I thought was bloatware).
Many laptops and I'm assuming prebuilt/preconfigd computers will have a hardware management utility installed that makes everything work efficiently. It responds to windows control panel settings or sometimes a GUI for the utility itself.
If you disable that power management thingie or uninstall it it can make your hard drives start snoozing. In my case the laptop would start making an annoying click as the heads reset because I had disabled the AcerPowerManagement utility (the first time this happened) or the utility simply wasn't present because of the clean install.
In the first case unblocking it fixed the issue (there was some other weirdness going on in regards to the actual provider of the utility going out of business or something so I think Microsoft themselves had to put out a patch) and in the secon ( the clean install) I simply had to download and install the utility from the Acer site then update Windows.
Then I just had to make sure in the Windows Power Management settings that the hardrives were set to NEVER go to sleep. This I believe can be achieved by simply setting the Power Management thingie to "Performance" but I prefer to go in and create a custom plan just to be sure.
I hope that helps and isn't too confusing/weird.
Also... howdy, Kenny. Gald to see you're still rocking' it. ;-)
